Why it works: Chocolate and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 10,020 recipes. Both carry sotolon, which smells curry, maple. The science ↓

Ingredients
Directions
The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the chocolate
Combine chocolate and enough water in a clean enamelled saucepan to prevent sticking. Dissolve over low heat.
Make the dough
Cream together butter and sugar in a bowl.
Beat in the egg yolk until well combined.
Slowly add the melted chocolate to the mixture and stir well.
Sift in 2 ounces of flour and beat again.
Work in the remaining 2 ounces of flour by hand until combined.
Roll out the dough lightly and stamp out biscuits.
Bake
Place biscuits on a baking sheet lined with greased paper.
Bake in a preheated oven at 400°F (200°C) for 5 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Good chocolate
- Provides the main flavour and, once melted, enriches the dough with richness and colour.
- Fresh butter
- Carries fat that creams with sugar to give the biscuits a tender, short texture.
- Castor sugar
- Creams with the butter to add sweetness and help create a light, aerated structure.
- Egg yolk
- Adds richness and fat, and helps bind the dough together.
- All-purpose flour
- Provides the structure that sets the biscuits as the dough bakes.
The step that matters
Dissolving the chocolate over low heat. Chocolate scorches and seizes when overheated. Gentle heat keeps it smooth and fluid, so it blends evenly into the butter and sugar mixture instead of forming lumps or a bitter, burnt taste.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
